不同覆盖方式对杨梅微环境与经济性状的影响OA

In order to optimize the existing cultivation techniques for Myrica rubra,this study used Biqizhong Myrica rubra as the test material to systematically compare the effects of greenhouse mulching with film,ground mulching with weed-control fabric,reflective film,and geotextile on the micro-environment and economic traits of Myrica rubra.The results showed that greenhouse mulching with film increased air and soil temperature,while reduced air and soil humidity.Ground mulching with geotextile decreased soil temperature and humidity.The highest commercial fruit rate of Myrica rubra was 80.46％under greenhouse mulching with film,followed by ground mulching with geotextile and reflective film,both significantly(p<0.05)higher than 61.72％in open-field cultivation.Compared with open-field cultivation,ground mulching with geotextile significantly improved fruit hardness,soluble solids content,and solid acid ratio.Considering the costs of different mulching methods,geotextile has low cost,solid and durable properties.Ground mulching with geotextile enhanced the commercial fruit rate of Myrica rubra,and its fruit quality was significantly better than other treatments,making it a key technical measure for open-field cultivation of Myrica rubra.
